TO 土老帽:
S"5</* hb_YdnG 1) Before you use any software, you'd better read some theoretical
3AX /A+2 :Oa|&.0l? books about finite element method for structure, for example the
}4A+J"M4y WASs'Gx book from Tsinghua Univ. is good one.

D-E30b]e 4=*VXM/ you can use some small finite element program to
.OXvv _?< C1r]kF solve beam or some structure problems for better understanding;

Ol{)U;,` `[VoW2CLH+ The very important thing is what's the problem you want to solve by
**fJAANc $-jj%x\} program? which method you like to use and which model is better

#N[nvIi} 6b6}HO in-site or measured data.
